To uit whom 'it may concern ide it known that 1, irlrrirn DrounMorir,` a citizen or the itepublic of France, and a resident of ille @ateauyDepartment of Nord, Francea have invented certain nen7 and useiul iiinproif'einents in ilirarnes for Beet-Harvesting' Machines, ot which. theiolloiving 1s a speciiieation. i i

'ifhe present invention relates to beet har vesting apparatus and particularly'to the construction ot the traine tor carrying' the harvesting.; apparatus. i a

in the accompanying illustrative enibodin nient ot iny inventioin ifigure 1 is an elevation ot a L,ie-row beet topper; i

lfig. 2 is a plan thereof.

The machine here shown comprises al trame 1 ot' channel iron mounted through bearings 3 upon the rotating` shaft 2p The latter is driven troni the supportinr wheels d through ratchet boxes 5 which permit the tvheels to rotate at dirl'erent speeds after the fashion ot a differential when rounding curves. rit the iront the traine is supported by a pair ot' steering Wheels G.

'this harvesting mechanism which may be oi various types, is shown mounted ona shaft 1S fixed to a stirrup 19 which is here shown as carrying` a beet top heading ltniie l'h The stirrup 19 is supported by an arni` Q0 pivoted to a pin 21 on the stirrup andto a sli-ait "22 rotating,l in bearings on the trarne. The shaft 18 is also pivoted to another arirr iireely mounted on a driving shaft 24e carried by the ltraine. The parts 18, 21 22`a"nd 2i (see Fig. 1) constitute the angular points ci" a parallelograni whiehuis tlexibleand the inorable sides oi which are formed by the stirrup 19 and arins 2O anc'l 235 the side 24E-Q2 being fixed and vertical. This ar rangement allows the niovable side 19 to always remain vertieai which insures a constant grip for the lrniie 17 whatever the height thereof above the zaround may be.

Bach heading wheel 1G is borne downs ward not only by its own Weight but also by the pressure ot a flat spring' 3( one end ot 'which bears upon the lever 20 and the other end oit which is tired to a rneinber 3S lreyed on the shaft Q2. This rnelnber 38 is provided with a lifting pawl which engages beneath the arm E20. 1t will be understood that under these circumstances the pressure ol the springs 37 upon the levers 20 can be regulated by the rotation of the shaft Specification of Iietters Patent;

22, and thus the pressure of the heading:

Wheels upon` the beet tops varied. Counter Weights 100 hired to stirrups 19 assist the action of the springs; The* rotation of' the shaft 22 also aiiows` the heading wheels to be raised for the purpose of transport or when the machine has arrived at the end of the iield. The rotation oi" the shaft 22 is obtained by means oa lever LO1 heyedupon it and which carries a nut 111 ipivoted* in its forked end 412.` i i `'This nut 11 is screwed intothe screw@` threaded end of a shaft 413 provided-With anwoperating hand Wheel 44:. This shaft` is capable of rotatingin a bearingvil which is `pivoted in its support. Then the hand Wheel et is rotated in the direction to raise the heading Wheels 16, the shaft 29j rotates the members 3S and with these latter the springs 37, so that the pressure otthese springs upon the arms 2O is removed. lThe lifting pawls 39 then liit the arms 2U and the stirrup 19 and the partscarried thereby are raised. Ar balaneingspring 11G iixed to1 theend of the lever lf2 and to the trarne"` facilitates the lifting operation. The head" ingdevioes are brought baolr into their op? erative position by a reverse action. `The tension of the springs* 37 is obviously `determined by the extent of rotation of the hand Wheel 44. Adjustablesereiv stops '17 bear upon the end of thestii'rups 23 and limit the `c'lescent of the heading` Wheels so that thereafter `further rotation of the Wheel 441 in the sainedirection increases the" pres-` sure eiterted by the spring 3T. 1

Various modifications" of the construction sl'iownf will` reaidilyoecur" to those skilled in the art without departing from What claim as myinventionzls- I claim 1. In beet harvesting apparatus, a ivheei supported frame, an upright rigid therewith, a second upright parallel thereto, linlrs pivotally connecting' said uprights to permit of a parallel-ruler motion of said second upright with reiation to the fixed upright, a harvesting device carried at the lower end of said. second upright, an operating hand screw, and a paivl operated thereby and engaging one of the linlr connections between said uprights to lift the movable upright carrying the harvesting tool.

2. In beet harvesting apparatus, a wheel supported frame, an upright rigid therewith, a second upright parallel theretoJ links piv (iii otally connecting said uprights to permit of a parallel-ruler motion of said second upright with relation tothe fixed'upright, a harvesting device carried at the lower end of said second upright, a spring adapted to exert downward.pressure on one of said link connections, an"operating hand'screw and means operated thereby for forcing said spring downward into pressure-exerting positi'on.y v

' 8. In beet harvesting apparatus, a .wheel supported frame, an upright rigid therewith,

a second upright parallel thereto, links pivotally connecting said uprights to permit of a parallel-ruler. motion of said second uprightl with relation to the xed upright, a. harvesting device carried at the lower end of said second upright, a lifting pawl adaptand said lifting pawl and pressure ed to engage one of the link connections, a

spring adapted to exert downward pressure on saidlink connection, a hand screw, and an `operative connection between the same and said lifting pawl and pressure spring,

' said connection 'being such that the lifting pawl is disengaged on the application of pressure from said spring, and the spring pressure is removed on the engagement of said lifting pawl, substantially as described.

5. In beet harvesting apparatus, a wheel supported frame, an upright rigid therewith, a second upright parallel thereto, links pivotally connecting saiduprights to permit of a parallel-ruler motion of saidV second upright with relation to the fixed upright, a, harvesting device carried at the lower end 0f said second upright, an operating hand screw, and a pawl operated thereby and cngaging one of the link connections between said uprights to lift the movable upright carrying the harvesting tool, together with a lifting spring operatively connected to said lifting pawl, substantially as described.

6. In beet harvesting apparatus, a wheel supported frame, an upright rigid therewith, a second upright parallel thereto, links pivotally connecting said uprights to permit of a parallel-ruler motion of said second upright with relation to the ixed upright, a harvesting device carried at the lower end of said second upright, a spring adapted to exert downward pressure on one of said link Connections, an operating hand screw and means operated thereby for forcing said spring downward into pressure-exerting po` sition, together with an adjustable weight on said movable upright to assist the action of said pressure spring.

7. In beet harvesting apparatus, a wheel supported frame, an upright rigid therewith, a second upright parallel thereto, links pivotally connecting said uprights to permit of a parallel-ruler motion of said second up right with relation to the lixed upright, a harvesting device carried at the lower end of said second upright, a spring adapted to exert downward pressure on one of said link connections, an operating hand screw and means operated thereby for forcing said spring downward into pressure-exerting position, together with a` stop limiting thc downward movement of the movable upright whereby the pressure of said spring` may be increased.
